This documentary covering the enormous world tour Katy Perry undertook in 2011 was surprisingly tame for a big music star behind-the-scenes film. There is virutally no bad language (one instance of a** and one bleeped out s***.) No drugs, no partying, nothing racy. Katy comes across as a sweet, determined, talented young woman, with a suppportive team of sister, best friends and others. They did discuss her strict Christian upbringing, and her parents were briefly interviewed. Though they didn't seem terribly thrilled by her choice of career, the movie doesn't get into that drama, if there is any. There's lots of eye-popping concert footage, and uplifting messages from Katy and her fans. Do be prepared that Katy becomes very distressed at the dissolution of her marriage. Though there aren't a lot of details, she is seen sad and crying, lying down and almost not able to go on with several shows due to upsetting messages with now ex-husband Russel Brand. She rallies, however, puts on a smile and gathers strength from her fans. I think kids 9 and over would do fine with this film. Younger ones might be upset at seeing Katy during her down times, and frankly, may get bored and restless. I saw a few younger kids looking pretty disinterested - the movie is mostly interviews and behind the scenes footage with concerts mixed in - no plot and no story of the kind kids younger than 8 are used to seeing. My own daughter, who is 9 and loves movies and Katy, told me it was "a little boring". I think I may have enjoyed it more than her! All in all, a pleasant, enjoyable look at a talented girl on her way to the top.
